ZÜRICH, SWITZERLAND / ACCESSWIRE / December 3, 2024 / NLS Pharmaceutics Ltd. (NASDAQ:NLSP)(NASDAQ:NLSPW) (NLS), a biopharmaceutical company, is pleased to share preclinical data demonstrating the potential of its dual orexin receptor agonist (DOXA) platform. AEX-41 and AEX-2, two first-in-class non-sulfonamide DOXAs, are designed to target both orexin-1 (OX1R) and orexin-2 (OX2R) receptors while concurrently inhibiting cathepsins. Cathepsins play significant roles in a variety of physiological processes and may offer a novel therapeutic approach for narcolepsy and other neurological disorders.
Key Preclinical Results:
The ongoing preclinical study, initiated in October 2024 at the Centre for Neuroscience Research of Lyon, one of Europe's premier neuroscience research centers, has produced compelling data:
Improved Wakefulness and Sleep Architecture: In orexin knockout mice, AEX-41 (administered orally at 40 mg/kg) demonstrated a significant increase in wakefulness and a reduction in REM sleep duration. These effects are crucial for managing the core symptoms of narcolepsy.
Comparable Efficacy to Selective OX2R Agonists: The efficacy of AEX-41 was comparable to sulfonamide-derivative selective OX2R agonists under similar experimental conditions, highlighting its potential as a versatile alternative for broader therapeutic application.
Multi-Pathway Potential: By targeting both orexin receptors and Cathepsin H (CTSH) inhibition activity, AEX-41 offers a dual-action mechanism that could address not only sleep-wake regulation but also underlying neurodegenerative processes.
Starting in 2025, NLS plans to expand its research to investigate the impact on CTSH in animal models of neuroinflammation, a key factor in the progression of neurodegenerative diseases. An Investigational New Drug (IND) application is planned for 2026-2027 to support this new avenue of study.
Eric Konofal, MD, PhD, Chief Scientific Officer of NLS and inventor of the DOXA platform, stated, "The dual mechanism of AEX-41 marks a transformative approach in treating narcolepsy. By simultaneously targeting orexin receptors and cathepsins, we aim to provide both symptomatic relief and disease-modifying potential- which would be an advancement over current therapies. In addition, based on cathepsins broad mechanism of action, we believe the DOXA platform may hold significant synergies with Kadimastem's pipeline, especially in the areas of diabetes, which is often associated with sleep-wake dysregulation manifesting as insomnia, as well as amyotrophic lateral sclerosis. ?
NLS is actively advancing the development of AEX-41 and AEX-2, with plans to further evaluate their safety and efficacy in clinical settings. Beyond narcolepsy, the company is exploring their potential application in other neurodegenerative disorders, including amyotrophic lateral sclerosis (ALS), leveraging their unique dual-targeting mechanism.
About Narcolepsy
Narcolepsy is a lifelong sleep disorder caused by the autoimmune-mediated loss of 70,000-90,000 orexin-producing neurons in the hypothalamus. It is characterized by excessive daytime sleepiness, cataplexy, and rapid eye movement sleep abnormalities, and is tightly associated with the human leukocyte antigen HLA-DQB1*06:02. Other predisposing factors for narcolepsy include associations with polymorphisms in the T-cell receptor alpha and beta genes, whose products recognize antigens presented by HLA molecules, and the CTSH gene.
